DISK DRILL.

Specification of Letters Patent.

Patented Jan. 23, 1906.

Application filed August 5, .1905. Serial No 272,879-

To all whom it may concern.-

Be it known that I, HENRY C. HAM, a citizen of the United States, residing at Liberty, in the county of Union and State of Indiana, have invented certain new and useful Improvements in Disk Drills; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters of reference marked thereon.

The present invention has for its object to materially improve the construction and o eration of a seeding-machine or disk drill 1n which simple and effective means are employed for mounting and spreading of the wings, a novel arrangement for raising and lowering the center double disk, and means for attaching and adjusting of the carryingtrucks, whereby a practically-operating disk drill is obtained which will possess both strength and durability as well as eflective in its action and providing a machine of this character that will combine many features of superiority in the several details of construction over the machines in ordinary use. I

The invention consists in a disk drill constructed substantially as shown in the drawings and hereinafter described and claimed.

Figure 1 of the drawings is a side elevation of a disk drill constructed in accordance with my invention; Fig. 2, a top plan view with the seed-hopper and connections removed, said view showing the two positions of the wings and their connections in full and dotted lines; Fig. 3, an under side plan view with a portion of the front end of the drill removed; Fig. 4, a vertical longitudinal section taken on line 4 4 of Fig. 2.

In the accompanying drawings, A represents two horizontal and parallel beams, which constitute in part the frame of the machine, and between and to these beams is journaled the driving-wheel B of any preferred construction, the two beams being held in place by the hitch-post a in front and the block b in the rear of the machine, said post and block being suitably bolted or otherwise connected to the beams, as found most referable. The axle c of the driving-wheel is suitably keyed thereto and has its bearings in brackets 01, provided with hinged caps 0, so that the caps may be raised to lubricate the bearings when it is found desirable. The

. brackets d are horizontally and longitudinally adjustable upon the beams A through the medium of a nut f engaging the screw end of a bolt g, which extends through an elongated slot h in the bracket, as shown in Fig. 2 of the drawings, the brackets having brace-rods i connecting thereto and to the hitch-post a in any suitable manner. I do not wish, however, to be understood as limiting my invention to the means herein described and shown for connecting to the beams the axle of the driving-wheel, as other means may be substituted without in any manner departing from the essential features of the invention.

A segmental or curved bar 0 is bolted or otherwise suitably connected to the beams A and to the block b, and said bar is also engaged with the outer wings D by adjustable guide-brackets E and with the inner wings F by similar brackets G. The brackets for the outer and inner wings are the same in construction and are adjustable upon the wings by means of bolts engaging elongated slots 7c, or any other suitable and well. known means may be employed that will enable the brackets to be adjusted to adapt them to the curve in the bar. The segmental or curved bar C has a guide-track Z, over which extends the overlapping flanges m of the brackets, so that when the wings move on the arc of a circle the Wings will be guided thereby.

The outer wings D are bolted or otherwise suitably connected to bars H I, the bars being arranged in pairs and pivotally connected in any suitable manner to the upper and under sides of the beams A, at or near the front ends thereof, and the opposite ends of the bars being connected to the upper and under sides of the outer wings D, the outer and inner wings being pivotallyconnected together by the straps i.

At or near the rear ends of the outer wings D are clip-plates n, secured thereto in any desirable manner, and with these plates are pivotally connected pitman-rods 0, the inner ends of said rods being in like manner pivotally connected to a link 10, and said link in turn is pivotally connected to the block b in any preferred manner. The inner wings F are pivotally connected to the link p by means of the straps g, which straps are suitably pivoted to the link and to the wings, as shown in Fig. 2 of the drawings, whereby both the outer and inner wings are operated,

I provide one of many means that may be employed for operating the link 19 and through said link and its connections with the outer and inner wings enable said wings to be moved outwardly or inwardly on the arc of a circle, said means in the present instance comprising the rotatable shaft J, to which the link is rigidly connected and-operated by a hand-lever K, suitably connected to the upper end thereof, as shown in Fig. 4 of the drawings. The lever K is spring-actuated through the medium of the coiled spring r, and when the wings have been adjusted by the action of the hand-lever the wings are held in their adjusted position by a tooth or projection 8 upon the under side of the lever engaging with a notched segment L.

The means herein described foroperating the movable wings through the medium of the lever and its connections with said wings.

may be variously modified or changed, as necessity would require, although such means as shown are considered the most simple and practical for the urpose intended.

The wings D carry the usual disks M N, respectively, and with these disks are the seed-boots O, which connect with the discharge-tubes P, and said, tubes. communicate in the usual manner with the seed-hopper Q, the seed therein being agitated and dis charged in the usual manner by a sprocketchain S, which chain engages a sprocketwheel 25 on the axle of the driving-wheel and upon a rotatable shaft under the hopper in the usual manner, this means being common in disk drills, and further reference thereto is deemed unnecessary. The seed-hopper Q has brace rods or straps u u, connected to the ends of the hopper and to the hitch-post a, and braces i i are connected to said hitchpost and to the bearing brackets d on the eams A, as hereinbefore described. Brace rods or straps 1) have their respective ends to each other, as shown in Fig. 3 of the drawings, the disks being adapted to raise up and down by connecting said disks to a verticallymovable frame V, the forward end-or the bars thereof being pivoted at :20 to the parallel beams A. The frame V may be of any suitable construction and the disks T rotatably connected thereto in any preferred manner,

and the means employed forraising and lowering the frame consists in part of a notched bar W, suitably connected to said frame and having a foot-pedal y upon its upper end for operating it. The notched bar W extends through a yoke 2, and when said bar is depressed to bring any one of the notches in engagement with the yoke the bar is held in its a justed position by a pivoted lock device a, and when brought up against the notched bar it will hold it in engagement therewith, and when the device is swung out laterally or horizontally away from contact .with the bar the same will be released, when it may be depressed or raised, as required.

To the rear end of the frame V are suitable hangers b for supporting the truck-wheels X,

said frame the construction shown and means employed may be subject to various modifications and changes, as any form of frame and means for raising and lowering the same that would successfully attain the object desired may be used. The truck-wheels X are connected with bars Z, and said bars are adjustably connected to the handles Y Y of the machine and pivoted thereto, so as to allow the raising and lowering of the wheels with the companion disks T.

The seed-hopper Q is sustained by suitable posts 61, connecting the beams A and the hopper, and the same is further held in proper position by the diagonal braces 6, connected thereto and to the handles Y, and to strengthen the curved bar C at its center a reinforce-block f is secured thereto, as shown in Figs. 2 and 4 of the drawings.

The seed-hopper Q has the usual slide 9 and lever 72. for operating it and may be constructed in the usual manner of hoppers used in this class of machines or constructed in such manner as may be found best adapted to the disk drill.

The outer and inner wings carrying the furrow-disks are pivotally connected with the parallel beams constituting the frame of the machine and with each other respectively, and by means hereinbefore described the outer and inner wings are moved simultaneously either out or in, as the case may be. The manner of pivotally connecting the forward ends of the outer wings to the parallel beams or frame of the machine near the front thereof enables a long swing to be given to the wings to prevent the disk angle from varying too much when the wings are moved out or in. The two inner wings being pivoted near the center of the outer wings, the forward part of the wings will be moved out about the same distance as will be the rear part IIC of the wings, which will cause a parallel movement and maintain the alinement of the disks. This feature of the invention, in connection with the short and long wings, is considered of material importance, and, as will be understood, the outside disks being mounted upon the long wings will swing out and in with little variation of alinement, and the next two disks upon the short wings being moved in a parallel manner, maintaining their alinement of the disks, are always the same relative distance from each other, thus making all rows of grain planted to be the same distance apart whether the drill is worked wide or narrow. The four disks connecting with the outer and inner wings are of the concavo-convex pattern and can be set to throw the earth outward or inward, as desired, by changing the position of the disks by reversing them. I

The two companion disks hereinbefore described, which may be termed the two center or double disks, have flat surfaces and are so mounted upon their bearings that their forward peripheries or edges will run together and the rear portions of the disks will be separated to present a space between the two to admit the dropping of the grain. The frame that carries the companion disks may be in the form of drag-bars, or any suit able means may be employed for ivotally supporting the companion disks f om the parallel beams of frame of the machine and from the notched bar hereinbefore described, thus allowing the vertical adjustment of the disks to set them at any required depth or to lower the disks to suit low places in the center of the corn row, this being an additional feature of importance.

The two truck-wheels mounted upon a suitable frame or hangers hereinbefore described, which are pivoted to the frame or drag-bars carrying the companion disks at the center of the machine, enable the wheels to be raised or lowered independent of the raising or lowering of the pivoted frame or drag-bars. The truck-wheels may be adjusted up or down as circumstances require through the medium of the bars that connect the same with the handles of the machine, said bars being adjustably connected to the handles, or any other suitable and well-known means may be employed for enabling the wheels to be vertically adjustable. The

truck-wheels and means for raising and lowering the wheels and holding them in their adjusted position enables the rear of the drill to be carried when not in use, and they are also used for regulating the depth of sowing, as the wheels can be adjusted to permit the disks to run deep or shallow, as desired.

The segmental or curved bar with guidetrack connected to the parallel beams comprising the frame of the machine, in addition to the guide-brackets engaging the track,

which brackets are secured to the pivoted wings, form together a means for securely holding in place and guiding the wings in their movement.

The brace rods or straps which are con nected to the boots of the outer disks and to the lower ones of the bars connected to the under side of the parallel beams serve as fenders to keep trash and cornstalks away from the two outer disks upon the outer wings.

The inner wings carrying the disks are much shorter in length than are the outer wings, and the manner of pivoting them to each other and the means employed for operating the wings are such that the inner wings will move half the distance that the rear of the outer wings are moved.

Having now fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a disk drill, a suitable frame and an inner and an outer wing upon each side thereof, an intermediate means pivotally connecting the outer wings with the frame, said outer and inner wings being of different lengths, disks connecting with the wings, an

operating means and an intermediate means connecting therewith and with the wings whereby said wings may be simultaneously operated, substantially as and for the purpose set forth.

2. In a disk drill, outer and inner wings and disks connecting therewith, said outer wings pivotally connecting with the frame of the machine and pivotally connecting with the inner wings, and means for operating said wings, comprising an upright operating-rod and means for operating it, a link connected to the rod and pitman-rods pivotally connecting with the ends of the link and with the outer wings, and connections pivotally engaging the link and pivotally engaging the inner wings, substantially as and for the purpose described.

3. In a disk drill, a segmental or curved bar secured to the frame of the machine and I having a guide-flange thereon, a plurality of pivoted wings of varying lengths, guidebrackets adjustable upon the wings and engaging the guide-flange upon the curved bar, and suitable means for operating the wings, substantially as and for the purpose specified.
